DCist brings to our attention Occupy Wall Street’s hopes for a spontaneous “Halloween night party” on Capitol Hill to “celebrate the wonderful Coke/Pepsi presidential election now in progress … and the honest, feisty way our elected reps in Congress have conducted our nation’s business … pay tribute to the bold visions they’ve put forward.” (Sarcasm, anyone?)

There’s a problem, however: Masks, which are a common sight at Occupy protests (see: Guy Fawkes), might be against the law.

“[A]s Capitol Hill is zoned as a residential neighborhood, the shrouds would violate a 2010 D.C. law, banning protesting while wearing a mask in residential neighborhoods,” writes DCist. “Under the Residential Tranquility Act of 2010, masked protesting in a residential neighborhood without first notifying police or between the hours of 10 p.m. and 7 a.m. is an arrestable offense. The law was pushed by Councilmember Mary Cheh (D-Ward 3), in response to a series of demonstrations by an animal-rights group that protested outside D.C. residents’ houses.”
